DistributionDecorator: Abstract DistributionDecorator Class

In distr6: The Complete R6 Probability Distributions Interface

Abstract DistributionDecorator Class

Description

Abstract class that cannot be constructed directly.

Details

Decorating is the process of adding methods to classes that are not part of the core interface (Gamma et al. 1994). Use listDecorators to see which decorators are currently available. The primary use-cases are to add numeric results when analytic ones are missing, to add complex modelling functions and to impute missing d/p/q/r functions.

Use decorate or $decorate to decorate distributions.

Value

Returns error. Abstract classes cannot be constructed directly.

An R6 object.

Public fields

packages
